ما توصّل إليه النقاش

• Heden digital motors such as the 26ve or 21ve are compatible with Preston hu1 and mdr1 follow focus systems.
• Preston systems require digital motors with encoders rather than analog motors with potentiometers.
• Most digital motors compatible with Preston systems use a Lemo 1B 7 pin connector, though this connector alone is not a reliable indicator of compatibility.
• Tilta motors have a Lemo 1B 7 pin connector matching industry standards but use different pinouts and control systems, making them incompatible with Preston systems despite their similar appearance.
• Heden M26PT and M28VPT combo motors have a Lemo 1B 7 pin connector but operate with analog potentiometers and tachometers for zoom or focus applications.

يعتمد على

• Heden analog P-series motors such as m28-vp and m26p do not work with Preston systems.
• The Micro Servo was a discontinued Preston product with different requirements.
• Tilta motors cannot be used as a substitute despite having compatible-looking connectors.
• The presence of a Lemo 1B 7 pin connector is not a definitive compatibility indicator.
